The router parses the GRH, strips the LRH, attaches a new LRH to the next 
hop with the contents of the LRH filled in per its internal 
policies.   Nothing more for the main packet processing.   The router 
interacts with each subnet's SM/SA to insure the path records can be 
provided to the CM to fill in the right information.
